Angelina Jolie has donated 100,000 dollars to the flood relief effort in Pakistan, according to reports.

The actress, who is a UN Goodwill Ambassador, has given the equivalent of £64,000 of her own money while calling on her fans to help raise funds, news agency AFP is reported to have said.

Her donation is being made through the United Nations, which has described Pakistan's worst humanitarian crisis as one of the world's biggest disasters, with some 20 million victims.

The Salt star's previous donations include one million dollars (£640,000) to help earthquake survivors in Haiti earlier this year.

At the London premiere of her new thriller Salt, Angelina urged people to donate, saying: "It is getting hard for people - they see Haiti, they see these other events ... and they get exhausted by the time another big one rolls around."
